IMPROVEMENT'IN CORN-cuLTlvAI-ORS.

` Specification forming part of Letters Patent No. 115,427, dated May 30, 187.1.

To all whom t may concern:

Be it known that I, GUsTAvs D. BROWN,

` of Lebanon, in the county of St. Clair and State oi' Illinois, have `made certain new and `useful Improvements in Corn-Cultivators; and

`I do hereby deelare that the following is a full and true description thereof, reference being had to the accompanying drawing and to the letters of reference marked thereon.

This invention consists chiefly in a new arrangement and combination of parts to achieve the lateral movement of the plow-frame and plows, to gage the depths of said plows, 'as

well as to the manner ofA laterally adjusting said plows to the plow-frame, all of which will now more fully be described. l

To enable those herein skilled to make and 1 use mysaid improvements, I will now more j `fully describe the same, referring tothe accompanying- Figure las a sectional elevation;` to Fig. 2

\ as a top plan; to Fig.3 as a rear-end view; to

` Fig. et as a detail part plan of the standardguid es.

` 1 support the rectangular frame A on wheels A' by sub-axles a, bolted properly. Said plowframe I further pivot `to the tongue B at b,

` the front timberv Working in a guide-strap, b', boltedlto said tongue. 0n top. the tongue or `draft-pole B I pivot a hand-lever, C, havin'g its-fulcrum pivoted at c to a segmental bar, C', bolted to the front timber of the frame `A,as shown in Figs. lland 3. The lever G extends back within operative `reachof the drivers seat. By means of saidA hand-lever the operator or plowman is readily enabled to guide the frame and its plows laterally, in accordan-ce withcroolred or irregular rows of corn.` ',Iheseat D I secure adjustably, `by

l means of bolts d and holes d1, to a rear proj jecting bar, D', as shown inFigs. 1 and 2. In

order, however, that said seat may be raised or lowered, I have arranged the seat-bar D' j convex at one end, (where it connects with the tongue B,)bein g secured by proper bolts, y in manner clearly indicated in Fig. 1. The

plow-frameA has two stirrups, d2 d3, for the .V feet of the plowman.`

It will be observed that as the plowman can vary the position of the seat, rai-se and lower the same, he can suit his weightaccordingly,

plow evenly7 and assist by his feet to guide the frame carrying the plows laterally, as the case requires. Theplows E are connected to the frame A, their standards E' passing through slotted standardguides F F', constructed and bolted to the frame A, as shown in Fig. l.

To adjust the plow-points as required, the standard-strap F on each end has a slot, f, as shown in detail, Fig. 4. Furthermore, in

order that said standardguides F F', with the plows E, can be adjusted and secured in varying lateral positions, I provide the frame A with a series of holes, f', as shown in Fig. 2.

To gage the depthV of the plows E their standards E', at their upper ends, are connected to the hand-levers Gr by swivel-joints g, said levers having their fulcrum at g1 o n the ratchet-standard g2, bolted to the frame A, and in which said levers engage and are held in any required position. The plows E are furthermore adjusted vertically by a series of holes, e, at their upper standard ends, in which the swivel-joints g can be properly inserted and secured.

To prevent the young corn from being covered Aby plowing, I have arranged the plowguides H, and secured the same adjustably to .the plow-frame A, in manner indicated in Figs.

1 and '3. The plows can readily be arranged to deposit the ground against the guides H or from the same, as required, by simply revers Y ing the position of the plows.

I d o not claim the manner of guiding the cultivator by leverage on the tongue, and all the other parts separately considered and. arranged; but

In a cultivator, the arrangement of standardguides F F' having slots f, plows E, standards E' having holese, hand-levers G, ratchet-standard g2, plow-frame A having holes f', tongue B, hand-bar (l, segmental bar C', seat bar D', and seat D made adjustable, when all said parts are constructed to operate as de scribed f In testimony of said invention I have hereunto set my hand.
